Abstract Two ground-based and two airborne cloud seeding events between 2003 and 2005 from a trace chemistry field experiment conducted by the Desert Research Institute (DRI) in the Payette river basin of Idaho are simulated by the Weather Research and Forecasting (WRF) model in Large Eddy Simulation (LES) mode with a grid spacing of 667-m using the recently developed Wintertime silver iodide ( AgI ) Seeding Parameterization (WASP, Xue et al., 2013a,b ). The WASP in WRF was specifically… CONTINUE READING
